Error: 1107, 2123, 3218, 5010 or 7003 appears during the network setup or when accessing internet content on the TV

    These errors may appear on your TV due to reduced internet speed, an unstable network connection, a device that disconnects from the network, or temporary interruptions from your internet service provider (especially when using wireless LAN).

    Follow these instructions to resolve the issue.

    Check your manual if model-specific information is needed to complete any step. Manuals are posted on your model support page.

    Check the connection after each step to see if the issue is resolved.

    1. Check that the TV is connected to the internet properly.

    Try one of the following steps (A or B) depending on your model:

    Step A

    1. Press the HOME button on the remote control.
    2. Select Settings.
    3. Select Network Setup or Network, and then select Network Setup.
    4. Select View Network settings and status or Network Status.
    5. Select Check Connection.

    Step B

    1. Press the HOME button on the remote control.
    2. Select Settings.
    3. Select System Settings.
    4. Select Set-up.
    5. Select Network.
    6. Select Network Setup or Network Set-up.
    7. Select View Network settings and status.
    8. Select Check Connection.

    If the connection diagnosis fails, then check your network connection settings.

    If the connection diagnosis passes and there is still an error message, then a software update may be needed.

    If the software update has been done and there is still an error, then power cycle the router, modem, and TV:

    1. Turn off the TV and unplug the power cord.
    2. Disconnect the router and/or modem by unplugging the power cords.
    3. After 2 minutes, connect the power cords for the router and/or modem.
    4. Connect the power cord and turn the TV on.
    5. After 5 minutes, try to Refresh Internet Content, which is available for TVs manufactured on or before 2014.

    2. Check the following settings and usage environment.

    Note: If the problem is not due to the TV, then the problem may be the network environment. These steps may help. For your router or modem devices, you may need to contact your manufacturer for details.

    1. Check the speed of the internet connection.  

    2. If applicable, eliminate duplicate routers.

    The router allocates IP addresses to devices when connecting to the internet. If two routers are installed, duplicate IP addresses may be assigned, causing error codes. Suspend the function of one router or uninstall it, checking to determine if the situation improves.

    3. Reset the TV to the original factory settings.

    4. Check the network connections from the entry of the home to the TV.

    The following diagram displays the flow of a network line from the provider to the TV or another device and includes points (A to D) as per below:

    You may be able to resolve the network speed issues by performing steps A to D:

    A. Network issues between the TV and the router

    B. Network traffic issues with other devices

    C. Network traffic issues at the ISP (Internet Service Provider)
